2 in 1 T&M instrument
OWON HDS1021M instrument combine digital oscilloscope and multi-meter.

High precision Multimeter function (3 3/4digits)
The HDS1021M handheld digital oscilloscope is equipped with Multimeter functions. It includes voltage, current, resistance, capacitance,dio-de test, continuity test. High resolution and precision design guarantee the accurate testing result. The user can choose the automatic or manual measurement according to different testing conditions.



Video Trigger
The HDS1021M handheld digital oscilloscope includes NTSC, PAL or SECAM standard video triggers which help to improve the efficiency obviously.


Observation for instantaneous signal
Digital trace mode is a function of analog oscilloscope recurs to the digital one. The function can show the waveform value which base on the time. It will help the user to find the irregular waveform and analyze the complicated dynamic signal. All of our products have the function to refresh the signal and therefore, can observe the instantaneous signal. The function is very useful to make adjustment for the tested system.


Average Acquisition Mode
This function reduce random noisy in the signal effectively and quite convenient for the engineer to analyze the waveform by. Below figure is the waveform which achieved after averaging which to show how this function reduces the effect from noisy directly.



Capture the pulse signals
The HDS3102M-N handheld digital oscilloscope provides single trigger function; it can capture the pulse signals once you set the instrument to trigger on a positive or negative pulse of a specified width.


Easy to distinguish the signal in any case
3.8” transflective TFT panel enables you to read the waveform clearly even single waveform under hard light. It’s quite useful for observation and analysis.
